Initial Comment: Ok,
After upgrading to Ubuntu Hardy I tried pd with jack and everything seemingly was working. Today I sat down to do some music using my external usb sound card (Edirol UA-25) and lo and behold Pd goes nuts. All afternoon I have tracked down these issues using Pd-0.40.3-extended-20080408-debian-stable-i386.deb from the autobuilds.
- the -jack startup flag does not work
- if using the -jack startup flag, trying using the jack selection in Media does not work, you cannot make the jack connection to work
- starting pd without the -jack startup flag allows you to select jack from Media and make the connection
- trying to connect to jack (once again from the Media menu) if its controlling an EXTERNAL audio device immediately slows down X to about 5fps and causes Pulseaudio to stutter. Everything is fine on killing pd.
As suggested by Hans, I tried a build before the recent jack bugfix patch (http://pure-data.svn.sourceforge.net/viewvc/pure-data/branches/pd-extended/v...) and I am able to connect to the external card running jack ... but the startup flag does not work.

OK, I have tested the 2 builds as suggested:
- Pd-0.40.3-extended-20080414-debian-testing * jack connection works fine, both on internal laptop and usb soundcards * the "-jack" startup flag fails making the jack connection and once pd starts, it cannot be started via the media menu either (the little check boxes in the jack popup are not checked, and checking them has no effect). pd has to be restarted without the flag and jack chosen through the menu for jack to work. * a little pulseaudio stuttering when pd first starts (but not a big problem, probably my slow laptop)
- Pd-0.40.3-extended-20080416-debian-testing-i386 * jack connection works on internal soundcard * jack connection on my usb soundcard does not work - choosing jack from the media menu causes either a segfault or a 5 fps X and heavily stuttering pulseaudio (running on the internal card) - once the popup appears things return to normal (the boxes are checked too), but performance goes crazy again once the popup is clicked - closing the pd window returns things to normal when the close pd dialog appears * jack startup flag still does not work as noted above * no pulseaudio stuttering on pd startup, just on pd exit

danomatika, could you try testing a build from 2008-04-14 and 2008-04-16, right before and after the commit that we think is causing the problem? That would remove a lot of variables as to waht might be causing this problem.

After a little testing today the -jack flag works fine using the earlier the Pd-0.40.3-extended-20080210-debian-stable-i386.deb build. So it must be something in the bugfix that messes up using external cards ...
